Brad Williams might have the most iconic voice in local music. Rangy and rarely onstage without a cowboy hat, the Salty Dogs front man sings in the kind of easy twang that comes from growing up in Marked Tree, but he tempers it with a big helping of Southern soul (you could imagine Williams doing right by a Dan Penn song). Williams and the Dogs — Brent LaBeau (bass), Bart Angel (drums), Nick Devlin (guitar) — often get pegged as “new traditionalists” or “honky-tonk revivalists,” which to these ears is just another way of saying country music that lasts. On Saturday, the band celebrates the release of its fourth album and first on Max Recordings, “Brand New Reason.” It's full of hot guitar licks, organ workouts and clever lyrics. The lead track, “Rock and Roll Will Never Stay,” offers a sly rejoinder to a preacher who's condemned rock 'n' roll. It goes like this: “We're living in one accord/we're living by the spirit and we're dying by the sooouul.” Stream it here. And get the CD at the reduced price of $8 at the concert.
